1916. Serial No. 107,311

To all whom it may concern;

. Be it known that I, CHAnLns J. KLEIN, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented new and useful Improvements in Electric Switches,

of which the following is a full, clear, conpresent application, is a division.

Although switches and has among its objects to provide a switch and a casing which may be readily assembled thereabout even after the former has been connected'in circuit.

Other objects will hereinafter appear.

in the accompanying drawing, wherein is illustrated 'an embodiment of the invention,

Figure 1 is a perspective view of the assembled switch and-casing;

Fig. 2 is a top plan view of the switch mechanism in position in the casing, the cap being removed;

Fig. 3 is a transverse sectional view on line 3 3, Fig. 1;

Fig. a is a top plan view and side elevation of one half of the casing;

Fig. is a top plan view and side elevation of the other half of the casing;

Fig. 6 is a side elevation of the insulating lining; and,

a Fig. 7 is a sectional view on line 7-7,

all

Fig. 6.

Referring to the drawing, and more par ticularly to Figs. 1 to 5, the casing comprises a pair of semi-cylindrical body portions 1, 2 which when united form a cylindrical casing for a switch b'ase3, and a pair 01' similarly shaped caps 4 adapted to engage about the respective ends of the said casing for maintaining the same assembled. The sections 1, 2 are provided with diametrically alined openings 5, 5 in their=sides through which the push buttons 6, 6 of the switch mechanism may pass, and one of said sections is provided with inturned longitudinal edges 7, 7 adapted to receive the correspond not limited thereto, this irivention is particularly adapted to feed-through ing edges 8, 8 of the other member for lock mg the sections together for mutual support thereof.

Forsupporting the switch base 3 within the casing the former is provided at its ends with laterally projecting lugs 9 which are received in openings 10 in the ends of the casing members, the metal of said members belng inbent as at 11 to increase the supporting surface.

A cylindrical resilient insulating lining 19. surrounds the switch base 3 to insulate the same from the casing and is provided with rectangular notches 13, 13 to receive the lugs 9, and with openings 14 to receive the push button members 6. The said lining is also slitted on one side through the openings 13 and 14, as shown at 15 in order to permit the same to be readily sprung about the base and the push button members carried thereby.

The caps 1 are provided with annular shoulders 16 which are adapted to receive catches 17 upon the ends of the casing members so that when the caps are forced down over the ends of said members they will automatically snap into locking engagement therewith and be held thereby. The caps are preferably provided with insulating linings and the conductors leading through the same are surrounded by insulating bushings 18 each of which is provided on its inner end with a flange 19 which serves to maintain the lining in position.

The respective ends of the switch base 3 The casing sections are then placed in position about the said lining in proper relation to the push button members and the lugs 9, the above operations bein capable of performance after the switch Ease has been attached to its conductors. The caps 4 are then snapped over the ends of the casing for holding the parts thereof securely-assembled A slight pressure upon the casing sections 1, 2-

is sufficient to release the catches 17 from the cap shoulder for disassemblmg the casing when deslred.

What I claim as new and desire to secure by Letters Patent is: v

' 1. In combination, a switch mechanism, a twopart longitudinally divided cylindrical shell inclosing the same, and a plurality of detachable caps for locking the parts of the shell together, said caps-having conductor openings therein.

2. Inv combination, an insulating base, a switch mechanism carried thereby, a two part cylindrical shell peripherally surrounding said base, and a plurality of detachable caps for locking the parts of said shell together, said caps being provided'with conductor openings.

' 3. In combination, an insulating base, a

plurality of push button operated switch mechanisms carried thereby, a two part cylindrical shell peripherally surrounding said base and having apertures through which the operating members extend, and a plurality of detachable caps locking the parts of said shell together.

4. In combination, an insulating base, a push button 0 erated snap switch mechanism carried tiereby, an insulating-sleeve surrounding said base and having apertures through which the push buttons extend, a two part "cylindrical shell inclosing said sleeve and having apertures registering with the apertures therein, and a plurality of detachable caps locking the parts of said shell together. a

5. In combination, a base, a plurality of switch mechanisms carried thereby, contacts for said switch mechanisms, terminal connections for said switch mechanisms at the ends of said base, and a casing inclosing said base and switch mechanism and having open ings in its side through which the operating members of said switch mechanisms extend and conductor openings in its ends communicating with said terminals.

6. In combination, a base, a switch mechanism carried thereby and having a reciprocating operating member projecting beyond opposite sides of the same, and a resilient insulating sleeve to surround said base, Said sleeve being longitudinally split at one side and aving a recess on a longitudinal edge to re- I ceive one end of Said operating member and an aperture diametrically opposite said recess to receive the other endof said operating member.

7. In combination, a substantially rectangular, base having projections at opposite ends,

overlapped and relatively projecting beyond opposite sides thereof, and a resilient insulating sleeve to surround the same, said sleeve being longitudinally split at one side and having an aperture to receive one end of said operating member and a recess on a longitudinal edge to receive the opposite end of said operating member.

9. In combination, a switch mechanism having a reciprocating operating member projecting beyond opposite sides thereof, and a resilient insulating sleeve to surround the same, said sleeve being longitudinally split at one side and having openings to receive the opposed ends of said operating member.

10. In combination, an insulating block, a switch mounted thereon and having a reciprocating operating member projecting laterally from said block and a tubular inclosing casing for said block and switch, said casing being divided longitudinally to enable assembly thereof about said switch and having an opening to receive said switch operating member.

11. In combination, a base, a switch mounted thereon and having a laterally extending operating member, a tubular inclosing casing for said base and switch, said casing being longitudinally divided for assembly about said switch and having an opening therein to receive said switch operating member and an insulating sleeve in: terposed between said casing and said switch.

12. In combination, a tubular casing divided longitudinally into separable sections, said sections having therein diametrically opposed openings, a base to be inclosed by said casing, a switch mounted on said base and provided with push buttons to project through said openings in said casing and an insulating sleeve surrounding said switch to insulate the same from said casing.

13. In combination, a terminal base, a two part longitudinally divided cylindrical shell inclosingthe same and a plurality of detachable caps for locking the parts of the shell together, said caps having conductor openingstherein.

14, In combination, a gitudinally split shell said shell having its terminal base, a loninclosing the same, adjacent split edges ofl'set to provide a flush joint, and means for retaining said edges in overlapping relation.

15. In combination, a terminal base, a longitudinally split shell inclosing the same, said shell having its adjacent split edges overlapped and certain of the overlapping portions offset to provide abutting shoulders for preventing contraction of said shell, and a cap fitted about said shell for preventing expansion thereof.

16. In combination, a switch mechanism having laterally extending push button mem bers, a longitudinally split shell inclosing the same, said shell having openings to re ceive said push button members and, having its adjacent edges overlapped and relatively ofi'set to provide abutting shoulders for preventing contraction of the shell.
